This is a differential drop kit that lowers the front differential to allow a higher lift on the front of the land cruiser (via torsion bars). The CV angles are reduced by lowering the front differential to reduce driveline fatigue. This differential drop is STRONGER than any other on the market and allows you to lift the vehicle from the diff drop. It may or may not work with other skidplates, but does have the OEM skidplate bolt hole locations. This is also a mount location for our UNDERWHERE Skidplates for the Land Cruiser.
